Abstract
Selon l'invention, la technique et le système d'analyse de la glycémie décrits par les présentes répondent au problème de l'interférence de l'hématocrite lors de la détection rapide de concentrations en glucose. Ils répondent à ce problème grâce à l'utilisation d'une technique de voltampérométrie d'impulsion différentielle dans laquelle des impulsions courtes de tension à haute fréquence sont appliquées pour maintenir la couche de diffusion au sein du réactif de l'électrode de travail et les impulsions sont appliquées sur une fenêtre (ou une plage) de tension limitée qui est au-dessous du courant limite de diffusion de crête. Les mesures au-dessous de la crête sont alors utilisées pour déterminer les concentrations en glucose. Grâce à cette technique, les concentrations en glucose peuvent être déterminées relativement rapidement (par exemple en 5 secondes) et indépendamment des niveaux d'hématocrite du fluide qui est analysé.
